From “global warming” to “climate change” to “ecosystem management,” the buzzwords have changed, but the issue remains: enthusiasm and hype are part of the PR machine that drives the public perception of science. When well-meaning activists rely on emotions as a shortcut to get the cooperation of the public, the fabric of civic discourse is weakened. Lovelock positions himself outside the debate.
Lovelock is a world-renowned scientist and environmentalist whose Gaia theory — that the Earth operates as a single, living organism — has had a profound impact on the development of global warming theory.

Having observed that global temperatures since the turn of the millennium have not gone up in the way computer-based climate models predicted, Lovelock acknowledged, “the problem is we don’t know what the climate is doing. We thought we knew 20 years ago.” Now, Lovelock has given a follow-up interview to the UK’s Guardian newspaper in which he delivers more bombshells sure to anger the global green movement, which for years worshipped his Gaia theory and apocalyptic predictions that billions would die from man-made climate change by the end of this century.
Lovelock still believes anthropogenic global warming is occurring and that mankind must lower its greenhouse gas emissions, but says it’s now clear the doomsday predictions, including his own (and Al Gore’s) were incorrect.
He responds to attacks on his revised views by noting that, unlike many climate scientists who fear a loss of government funding if they admit error, as a freelance scientist, he’s never been afraid to revise his theories in the face of new evidence. Indeed, that’s how science advances. —Green ‘drivel’ | Columnists | Opinion | Toronto Sun.

Locally it's easy to see the changes. First time in (at least) the last 40 years salmon fly fishing is closed in the Miramichi area (Canada, NB) because of low waters. Water is low but also too hot for the salmons to survive so they stay in the sea and therefore cannot reproduce themselves.
